PEDAL ATTAC'I'IM'ENT FOR A GELEB ATING LEVE3 S.

Application filed June 1,

r c all whom it may concern.

Be it known that l, Lustre- S. I'IAGKNEY, a citizen of the United States, residing at isadcna, iii-the county of Los Angeles and of California, have: invented new and l In'iprovemcnts in Pedal Attachments ccelerating Levers, o l? which the fola specification. lily invention relates tov improvements in pedal attachments" for accelerating levers i .iich are employed to control the operation of motive power in motor vehicles. It is customary for the operator to place hold the. sole or his shoe against an accelerator or throttle controlling lever and in doingso to tiltingly support his foot either at. the heel upon "foot board or near one side upon a supp rt provided for that purpose. This pr i-ce has been disadvantageous beuse it impairs uniformity of controland ratigues the foot of the operator.

funon the objects ot my invention is to provide an in xpensive antifriction device on the accelerator lever against which the drivers toot may rest freely in natural position at all times with reduced friction, thus eliminating toot strain and providing greater uniformity of operation of said lever and running of the vehicle. Among additional objects are greater simplicity of construction and effectiveness in use than heretofore. This invention is an improvement upon the construction set forth in Patent Number 1,214,027, issued to me on the 30th day of January 1917.

Further teatures of advantage of my invention will be apparent from thefollowing description.

In the drawings, Figure 1 is a perspective view showing a portion of the foot board of a motor vehicle through which the customary accelerating lever projects and upon which lever my improvement is shown mounted; F 2 is a plan of my improved device before it is applied for use upon the accelerator lever; F 3 is a sectional view taken upon the line 38 of Fig. 2; Fig. 41 is a section taken on the line 14 of Fig. 1 showing an alternative construction of my invention; Fig. 5 is a side elevation of another alternative construction of my invention before it is attached to the foot lever; Fig. 6 is a perspective view showing a portion of another form of accelerator lever and my invention applied thereto, and Fig.

T is another perspective view of an accelerator lever and my invention. applied. thereto. 1 In the drawing A indicates a portion of the foot board. of a motor vehicle having a slot therein through which projects the usual accelerator lever B, having a foot pedal plate 0 of elongated shape, This lever and pedal plate may be of any suitable e and construction my improvement bem applicable for use under varying conditions. As shown in. Figs. 1, 2- and 3 my improvement comprises a thin base plate 12, from which bearings 13 are struck up to journal an. anti-friction roller 14 therein above the plate. The base plate is shown formed with a plurality of radiating itastening armsv 15-which are adapted to be turned down and under the Sideedges' 16 of the j edal plate to secure the device on the sum i e of. the accelerator lever. Thus the deis easily and quickly applied to the accelerator pedal. Due to the curvature of the side edges or" the pedal plate the device is prevented from slipping longitudinally along and oil? of the pedal. In use the sole ot the shoe is pressed down upon the antifriction roller and due to reduced friction the accelerator lever is more evenly con trolled and foot strain relieved. To reinforce the base plate a washer 17 may be secured thereto by clips 18 struck down and under the edge of the washer (see Fig. 3). The base plate and its arms are of such construction that the device can be easily fastened securely upon an elongated, round or any other shaped pedal plate, the tour points oft fastening being effective for the purpose set forth.

hen desired the base plate 12 may be provided with other forms of antifriction means than the clips 15 and roller 1 1 and it is not intended that the invention shall be confined to the specific construction shown. In Fig. 4 I have for illustration shown a modification oi the clan'iping mea: in which pairs of clamping elements 22 and 23 are provided which are adjusted by means of the threaded key operated bolts 19, and in Fig. 5 I have illustrated the use of an antifriction ball movably held in the socket 21 on the" base plate 12.

In Fig. (3 I have shown an accelerator lever 24 formed with a round shaped toot piece or pedal 25 to which my improved device is shown attached, and in Fig. 2" I have illustrated another form of foot lever 26 having a bifurcated upper end between the branches 27 of which a pair of antifriction rollers 28 and 29 are shown journaled. These rollers form antifriction means for the sole of the shoe to press against as in the structure above particularly described.

It is not necessary to confine the use of the device to the direct application of the sole of'the shoe of the operator against the antifriction roller or ball, the invention permitting of the use of an auxiliary foot pedal when desired of the character set forth in Patent Number 1,214,027 above referred to.

In accordance with the patent statutes, I have described the principles of operation of my invention together with the structure which I now consider to represent the best embodiment thereof but I desire to have it understood that the construction shown is only illustrative and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In combination with an accelerator foot lever, a rotatable antifriction device, a support in which said rotatable device is journaled, means on said support for clamping the device to said foot lever and a device secured into said support for reinforcing its strength.

2. In combination with an accelerator foot lever, a roller, a support formed with bearings turned up from its body in which said roller is journaled and with arms adapted to be bent down and under said foot lever to secure said support thereon and a member fastened into said support for reinforcing its strength.

3. In combination with a foot lever, a roller, a supporting plate formed with bearings struck up from its body in which said roller is journaled and with arms adapted to be secured over said foot lever to hold the supporting plate thereon and a member fastened into the body of said supporting plate to reinforce its strength.

at. In combination with a foot lever having opposite edges, each edge protruding outwardly between its extremities, a supporting plate having four fasteners spaced apart and arranged to embrace said lever with said protrusions between pairs thereof to prevent disengagement of the plate from said lever, a rotatable antifriction member mounted upon said plate and means fastened into said plate for reinforcing its strength.

In witness whereof I have signed my name to this specification.
